Uveitis Course - Dr Eman Abdullatif

Lecture 1

Posterior Uveitis 

Please do not prescribe emprical treatment for uveitits patient, this will mask the symptoms 

كل تفكيري مع المريض ده في التشخيص الصح مش العلاج 

Optic nerve may not be involoved in MS 

Toxoplasmosis is a cause of retinal vasculitits 

Affect retinal artery and veins 

Vasculitis is a pathology of the wall 

occlusion is a pathology of the lumen 

ممكن يحصلوا مع بعض وممكن لا 

 Occulsion without inflammation may be BRVO

rare to see CRVO dt toxoplasmosis

Do not vitritis dt uninvolvement of the vitrous 

Intermediate uveitis only can cause vitritis 

You can say vitrous infiltration if it is not intermediate uveitis 

Sarcoidosis is one of the causes of exudative vasculitits but not the only cause, TB is one of the causes 

Sarcoidosis causes candle wax drippings 

متحفظش أي حاجة في ال uveitis 

المعلومة الرمادي اللي مش فاهمها فيها متشتغلهاش

Recurrent BRVO is Behcet disease till proved otherwise 

Lecture 2 

it is so hard to see normal choroid in a normal patient

Factors affecting the choroid:

Long term or short term

Long term: Myopic patient - thinning of the choroid due to overstretching of the layer to cope with the axial length

Short term:

Drinking water: increase the thickness

Drinking coffee: decrease the thickness

Smoking: Decrease the thickness

بلاش الحجات دي من 3 الي 4 ساعات قبل الفحص

We should exclude that before attributing any change in the thickness to the pathology

Difference between Choroiditis and Retinitis: 

Choroiditis: 
Lesions are more yellowish 
Retinal vessels are uninterrupted
lesions are well defined


Retinitis:

Lesions are more whitish
Retinal vessels are interrupted
Lesions are ill defined


There is overlap sometimes:
in deep retinitis, the retinal vessels are uninterrupted

Choroiditis Lesions:

one lesion - small: Focal Choroiditis
2 lesions or more- small : Multifocal Choroiditis
1 lesion - large : Geographic
2 lesions or more  - large: Disseminated (TB- AIDS)
Multifocal serbiginous Choroiditis : TB


vitrous cells is not an indication of activity and absence of vitrous cells is not an indication of inactivity


Birdshot Retinochoroidopathy usually misdiagnoesd with Harada

1 single pigmented lesion in the fundus exclude Birdshot

Birdshot is lesions of the inferior and nasal quadrant 

Cream colored lesions not chalky white 

Lesions are oval, elongated, fusiform , ms form 

مهم جدا أوسع عين المريض للتشخيص
